IOE-MAKIN Gr APPARATUS.

To all whom it may concern:

Be it known that I, WILHELM Gnmssnn, a citizen of the United States,residing at Denver, in the county of Denver and State of Colorado, haveinvented new and useful Improvements in Ice-Making Apparatus, of whichthe following is a specification.

The present invention has reference to improvements in ice makingapparatus, and more especially in the formation of the building, room orother structure wherein the freezing operation and the subsequentre-cooling of the refrigerating medium take place.

It resides primarily in the provision of a refrigerating structurecontaining separate tanks or chambers for the carryingout of the twooperations specified, the arrangement of parts being such that thebrineis caused to circulate through the freezing tank or chamber, and, onleaving that chamber, to enter a second chamber or tank wherein it iscooled and then discharged into a pump or similar operating elementwhich again forces it into the freezing tank. By reason of thisarrangement, the employment of cooling coils, or the like, in thefreezing tank or chamber is obviated, and, in consequence, the troubleand difliculty ordinarily attendant upon the cleaning and repairing ofsuch coils.

The invention also comprehends certain further improvements, hereinafterspecified, in the construction of the tanks or chambers themselves andthe therewith directly associated parts or features.

A structural embodiment of the invention is illustrated in theaccompanying drawings, wherein-- Figure 1 is a plan View, with partsbroken away and in section, of the improved freezing and brine-coolingtanks. Figs. 2, 3 and 4 are fragmental vertical sections on enlargedscales taken, respectively, on the lines 22, 3-3 and 4-4 of Fig. 1; Fig.5 is a fragmental perspective view, partly in section, showing theconstruction of one of the main supporting beams employed in thefreezing-tank; and Fig. 6 is a perspective view of one of the connectingbeams associated with said main beams.

The structure shown in the said drawings is designed primarily for themanufacture of the so-called can ice, but the circulating systememployed may be used with equal facility in manufacturing plate ice,

and it will be understood, therefore, that such of the appended claimsas relate to said system convey no specific limitation to the making ofeither kind of ice. Said structure'is preferably built or constructed,in the main, of concrete, and comprises essentially the two side walls 7and 8, the outer end wall 9 and the bottom wall or foundation 10, theseveral walls having their inner surfaces preferably lined or faced withterra-cotta tiles or the like, as indicated by the numeral 11, whichare, in turn, faced with a layer 12 of cement or concrete. The bottomwall 10 is also preferably provided with an insulating filling 13 ofcinders or the like. Between the two side walls extends a transversepartition wall 14 which forms the inner end wall of the several mainchambers or tanks hereinafter described and is constructed in the samemanner as the other walls, the said side walls and the bottom wall beingextended beyond this wall or partition until they'meet the inner endwall (not shown) of the building proper. Thespace inclosed by the walls7, 8, 9 and 14 is divided longitudinally by a main partition wall 15,one of the two chambers thus formed (indicated by the numeral 16)constituting the freezing chamber, while the other chamber is dividedlongitudinally by a wall or partition 17 to produce the brinecooling anddischarging chambers 18 and 19.

The freezing chamber is roofed by a grid like structure 20 comprisingmain beams 21 and crossor connecting-beams 22. The beams 21 are, in theconstruction illustrated, arranged transversely of the chamber, andtheir ends are supported in seats or pockets 23 formed in the walls 8and 15; they are preferably constructed in the manner shown in'Fig. 5,and consist each of a skeleton frame work of metal, and a filling orbody of cementitious material 24. The said frame work itself comprisesupper and lower pairs of longitudinally-arranged angle bars 25 and 26connected together at intervals by straps 27 and cross-bars 28, a seriesof longitudinally-arranged tie-rods 29, and a similarly-arrangedundulatory tie-rod 30, the frame work being placed in a mold which issubsequently filled with the cement or concrete. The upper portion ofeach beam is slightly reduced in width to produce the continuouslongitudinal shoulders 31 upon its opposite side faces, the latter beingalsoformed at intervals with vertical seats 32 and 33; the seats 32terminate short of the bottom face of the beam to produce the shoulders34, while the seats 33 have the shape of a bayonet-slot. The cross-beamsare in the form of separate blocks whose endsfit in the seats 3'2 andare supported upon the shoulders 34.

The above described arrangement of the beams comprising the grid 20 issuch that a series of rows of spaces or compartments will be produced,the side walls of each compartment being provided with centrally locatedseats 33. In each compartment is disposed a suitable can 35 whose tophas secured thereto a bar 36, or the like, the ends of which are engagedand held in place in the horizontal arms or branches of said seats,thereby maintaining the can in properly submerged position. The cansare, however, omitted and replaced by other suitable devices where themanufacture of plateice is contemplated, as will be understood. The gridis floored over in the usual manner by the removable covers 37 whichrest upon the upper faces of the beams 21 and, also, upon the shoulders31.

The brine or other refrigeratingmedium is supplied to the freezingchamber 16 from a longitudinal pipe 38 arranged between wall 8 and thefirst longitudinal row of cans and provided with a series oflaterallydirected nozzles 39 corresponding in number to the number ofcans in such row. Said pipe extends at its inner end through an openingin wall 14 and is jointed at that point to a pipe 40 leading from aforce pump 41 or like motive element arranged within a chamber 42located at one end of the cooling and discharge chambers 18 and 19. Thispump may be of any suitable type and may be driven in any preferredmanner.

The brine flowing through the nozzles 39 into the freezing chamber,fills the latter and surrounds the cans therein up to a pointapproximately level with the lower faces of the pockets 33, the wall 15being formed at about the point indicated with a series of openings 43through which the brine flows into the cooling chamber 18. Through thischamber extends a cooling device 44 here shown as in the form of alongitudinal drum or cylinder containing a refrigerating medium, thebrine, which. has become heated during, its passage through the freezingchamber, being re-cooled on coming into contact with said device, aswill be apparent.

The wall 17 which separates the cooling and discharging chambers, isformed at its bottom with a series of outlet apertures 45 through whichthe cooled brine flows into the discharging chamber. In said dischargingchamber there is provided a vertical partition wall of concrete 46 whosetop edge lies in the same horizontal plane as the bottom faces of theopenings 43, between which wall and the adjacent wall 7 is formed adownwardly inclined gutter or trough 47 opening at its lower end throughwall 14 into a pipe or spout 481 that leads into pump 41. The twochambers 18 and 19 may be roofed over with a covering of removablesections 49 similar in thermain to the covers 37 and provided for muchthe same purpose, the said covers 49 being supported upon the shoulderedupper ends of the walls 15, 17 and 7; Said chambers may also be providedwith intericrly-located braces 50 designed to strengthen the walls 15,17 and 46.

The operation is substantially as follows: Brine is forced from pump 41through pipe 40 into the. pipe 38, from which latter it flows throughthe nozzles 39into chamber 16, filling the same and freezing the watercontained in the cans. From said chamber it flows through the outlets 43into the chamber 18, wherein it is cooled by its passage around the drumor other device 44. On leaving chamber 18 through the outlets 45, itfills chamber 19 and overflows into the trough or gutter 47 whence it isreturned to said pump and again forced into pipe 38 for re-circulation.

It will be observed, therefore, that a continuous circulation of thebrine is provided for, during which time it is re-cooled upon leavingthe freezing chamber. Also, the disposition of the cooling device in achamber separate from that wherein the ice is formed enables such deviceto be readily inspected and cleaned, thus reducing the time consumed insaid operations and obviating the difficulties ordinarily connected withthe same. The building itself possesses a maximum degree of strength,rigidity and durability, owing to its substantially integral formation.
